Raging Bull has wicked power. Juan Manuel Lopez has wicked power, but we havent seen if he can wield it effectively against skillful opposition. Same story for Valero, clearly wicked power but not tested.

Agree, pac def has great punhcing power, but its not one punch and the fight is over style. The two im stuck between are Juanma and Arthur Abraham, both of these dudes can end the fight with one punch and they usually do.
